A Bard’s Beloved

If you find yourself in the southeastern part of Ard Skellig, head east from the Palisade along the path through the woods, then turn northeast and look for a secondary track that leads to the entrance to a cave.

When you enter the cave, you will hear the cries of a troubadour. He will implore you not to wake his "belowed". Go deeper into the cave until you reach its end. You will wake a grotesque and contorted creature. It seems that the troubadour’s "beloved" is a water hag. Kill her and collect the ingredients from her corpse. The troubadour will disappear and the quest will end.
